Title: Capstan speed controller
Inventor: OOTA YUTAKA
IPC: G11B15/46
Filed: 1985-11-27
Abstract: PURPOSE:To realize a stable slow motion reproduction by obtaining the mean value of plural pieces of sampled/held error information and changing the reference voltage of a drive circuit by an amount corresponding to the difference between said mean error and the prescribed speed error value. CONSTITUTION:Whether a slow motion reproduction state exists or not is descriminated by an error detector 8 to which the digital speed error signal (c) obtained from a digital frequency discriminator 1 is inputted. Then the detector 8 outputs the center value to a D/A converter 9 in the form of the output signal (j) if the slow motion reproduction state is not confirmed. If this reproduction mode is confirmed, it is descriminated whether a capstan motor 6 is driven at a fixed speed or not in an intermittent drive mode. If the constant speed drive state is confirmed, the digital error signal is sampled and the value of this signal is written to a memory. This action is repeated by the fixed frequency to obtain a mean speed error S. When the error S is larger than the maximum speed error Smax, the output value (j) is decreased just by 1 since the speed is less than the set level. Then the motor 6 is accelerated. While the motor 6 is decelerated when the error S is smaller than the minimum allowable error Smin.

Filed: 1988-10-21
Abstract: PURPOSE:To place a laser in a free position and to decrease the constraint in case of designing a system by providing a beam splitter for splitting an emitted light beam of the laser into two by a transmission and a reflection. CONSTITUTION:From a longitudinal Zeeman laser 1 of an He-Ne laser, circularly polarized light beams of the right turn and the left turn whose frequencies are different by about 1.8MHz obtained. These right and left circularly polarized light beams become linear polarized light components whose planes of polarization are orthogonal to each other by a 1/4 wavelength plate 2, and split into half each, respectively by a beam splitter 3. In this case, from a reflecting component of the beam splitter 3, a beat signal (f1-f2) is obtained as a reference signal in a detector 4. On the other hand, a frequency f1 of a beam emitted from a fiber 15l is reflected, for instance, by a Littrow reflector 8 which is brought to reciprocating movement such as an X stage of XY stages, subjected to a Doppler shift thereby and becomes f1+ or -DELTAf. Subsequently, by comparing it with said reference signal (f1-f2), DELTAf is derived, and since V is known thereby, the variation quantity of a position is known.

Title: Method and device for extrusion-pressing mixture consisting of vegetable small piece and binder
Inventor: ANTON HETSUGENSUTARAA
IPC: B27N3/14
Filed: 1984-12-21
Abstract: Extrusion of a mixture of vegetable bits with a binder, particularly wood chips with a weather-resistant binder, involves precompressing in a compression chamber of an extrusion press the mixture by a compression stroke transverse to the extrusion axis, the compression stroke being delivered by at least one precompression piston. Prior to the precompression elongated bits of the mixture are acted on by an orienting influence so that the elongated bits are deposited substantially parallel to the extrusion axis. The outer layers of the mixture are compressed with a reduced precompression ratio so that the bits oriented prior to precompression remain fixed in position during the subsequent extrusion stroke. Preferably the elongated bits in the mixture are oriented by free fall of the mixture through a plurality of upright, thin-walled bars of approximately equal height positioned above the compression chamber during filling of the extrusion apparatus by a mechanical hopper moving to and fro over the bars continuously.
